The San Diego Zoo on Tuesday revealed the name of its 15-week-old giant panda cub: Xiao Liwu, which means Little Gift.

By Chinese tradition, giant pandas are not named until they have been alive for 100 days. The announcement was made at the zoo's Hunte Amphitheater on Xiao Liwu's 107th day alive.

Baby Panda Makes Zoo Debut

Xiao Liwu was born to the zoo's Bai Yun on July 29 -- the famed mama's sixth cub -- and has become a tiny, furry celebrity.

Last week, the cub received his 12th weekly veterinary exam (as seen in video below) getting a clean bill of health. Doctors at the zoo said the 9.2-pound, 23-inch-long cub was "doing great."

He was pushing up onto all four legs, but wasn't quite walking yet, doctors said. His first teeth were getting ready to come through, and he was beginning to focus his eyes on people and things around him with recognition.

The San Diego Zoo is one of four in the U.S. that keep giant pandas for research purposes. Around 1,600 are believed to be left in the wild in their native China.
